Norbornanoid Chiral Ketones by Desymmetrization of Dibromoalkenes

New optically active polycyclic ketones 6a-6d, amenable to a large variety of synthetic applications, have been prepared from readily available 2,3-dibromonorbornene and analogs (Scheme 2) via desymmetrization with (-)-ephedrine, followed by hydrolysis under mild acidic conditions. At variance with substrates 4a-4d, the sterically hindered norbornene derivative 4e reacts with the solvent N-methylpyrrolidin-2-one (NMP) leading to the formation of the unusual cyclopropanoid products 8a and 8b.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 6704-31-0. Computed Properties of C3H4O2.

Chemometrics-assisted spectrophotometric method for simultaneous determination of Pb2+ and Cu2+ ions in different foodstuffs, soil and water samples using 2-benzylspiro [isoindoline-1,5 ‘-oxazolidine]-2 ‘,3,4 ‘-trione using continuous wavelet transformation and partial least squares – Calculation of pK(f) of complexes with rank annihilation factor analysis

A new multi-component analysis method based on zero-crossing point-continuous wavelet transformation (CWT) was developed for simultaneous spectrophotometric determination of Cu2+ and Pb2+ ions based on the complex formation with 2-benzyl espiro[isoindoline-1,5oxasolidine]-2,3,4 trione (BSIIOT). The absorption spectra were evaluated with respect to synthetic ligand concentration, time of complexation and pH. Therefore according the absorbance values, 0.015 mmol L-1 BSIIOT, 10 min after mixing and pH 8.0 were used as optimum values. The complex formation between BSIIOT ligand and the cations Cu2+ and Pb2+ by application of rank annihilation factor analysis (RAFA) were investigated. Daubechies-4 (db4), discrete Meyer (dmey), Monet (morl) and Symlet-8 (sym8) continuous wavelet transforms for signal treatments were found to be suitable among the wavelet families. The applicability of new synthetic ligand and selected mother wavelets were used for the simultaneous determination of strongly overlapped spectra of species without using any pre-chemical treatment. Therefore, CWT signals together with zero crossing technique were directly applied to the overlapping absorption spectra of Cu2+ and Pb2+. The calibration graphs for estimation of Pb2+ and Cu2+ were obtained by measuring the CWT amplitudes at zero crossing points for Cu2+ and Pb2+ at the wavelet domain, respectively. The proposed method was validated by simultaneous determination of Cu2+ and Pb2+ ions in red beans, walnut, rice, tea and soil samples. The obtained results of samples with proposed method have been compared with those predicted by partial least squares (PLS) and flame atomic absorption spectrophotometiy (FAAS).

Comprehensive monitoring of MEA degradation in a post-combustion CO2 capture pilot plant with identification of novel degradation products in gaseous effluents

A pilot plant campaign was performed to study MEA degradation in CO2 capture conditions and anticipate potential degradation products emissions to the atmosphere in industrial case. Aqueous 30% wt MEA was cycled between absorption and regeneration steps during 1700 h in the presence of a synthetic flue gas containing 81% of N-2,14% of CO2, 5% of 02,97 ppm of NO, 9 ppm of SO2 and 5 ppm of NO2. Specific methods (sampling, sample conditioning and analysis) were developed to improve degradation products identification and to provide a quantification of targeted compounds in liquid phase and above all in absorber and stripper gas effluents. Especially, trace elements were detected in liquid phase thanks to Head Space Solid Phase MicroExtraction (HS-SPME) and liquid-liquid extraction with ChemElut cartridges and in gas phase thanks to adsorbent tubes of different type: Sep-Pak for aldehydes and ketones, Orbo 60 for N-nitrosodimethylamine, Tenax and active charcoal for non-specific adsorption. 32 degradation products were identified in liquid phase and 38 in gas phase, 17 of which for the first time, especially derivatives of pyridine and oxazolidine, 1H-pyrrole and a new nitrosamine, the N-nitroso-2-methyl-oxazolidine.

Pd-Catalyzed Decarboxylative Cycloaddition of Vinylethylene Carbonates with Isothiocyanates

An efficient route for formal [3 + 2] cycloaddition of vinylethylene carbonates with isothiocyanates was developed for the synthesis of 1,3-oxazolidine-2-thione derivatives. The zwitter-ionic pi-allyl palladium intermediates formed in situ by decarboxylation of VECs acted as the three-membered synthons. In this transformation, the C-N bond formation was selectively realized over the C-S bond formation.

Preparation of Enantiomerically Pure beta,beta-Diaryl beta-Hydroxy-alpha-Amino Acids and Evaluation of Their Potential as Organocatalysts

A general synthetic procedure was developed for enantiomerically pure beta,beta-diaryl beta-hydroxy-alpha-amino acids 5, starting from readily available oxazolidine ester 1 and a wide variety of Grignard reagents. The problematic oxidative decomposition of beta-aminodiols 3, due to their instability in the presence of metallic oxidants, was successfully suppressed using Parikh-Doering oxidation and subsequent Pinnick oxidation. Additionally, the organocatalytic ability of beta,beta-diaryl beta-hydroxy-alpha-amino acids 5 was evaluated with respect to asymmetric fluorination of 2-phenylpropionaldehyde 6, and moderate enantioselectivity, 61%, was achieved using compound 5 f.

A general strategy to increase emission shift of two-photon ratiometric pH probes using a reversible intramolecular reaction of spiro-oxazolidine

Fluorescent pH probes have been served as powerful tools in biological and pathological studies in recent years due to the important roles of pH values in various physiological processes. Although plenty of pH probes have been delivered, development of two-photon ratiometric pH probes with large emission shift for detecting the variation of intracellular pH values is still a greatly challenging task. To address this concern, in this work, we have discovered a general strategy designing pH probes by means of a pH-dependent reversible intramolecular reaction of spiro-oxazolidine which can efficiently change their conjugation length and the electronic effect con-currently. To display the generality of the strategy, we have synthesized six pH probes, and all these probes exhibit short emission in basic conditions and dramatically red-shifted emission in acid environments. The emission shift of the six probes is more than 150 nm and even up to 210 nm, much larger than shift of all commercial and reported pH probes. The chemical sensing mechanism of intramolecular ring opening/closing reaction of spiro-oxazolidine has been confirmed with H-1 NMR spectra and density functional theory (DFT) calculations. Finally, we have used one of six with oneand two-photon properties to successfully image lysosomal pH changes under confocal and two-photon microscopes in a ratiometric manner. We believed that this spiro-oxazolidine strategy can serve as a general and powerful platform for the design of ideal pH probes. (C) 2020 Elsevier B.V. All rights reserved.

Enantioselective Synthesis of beta-Allenoates via Phosphine-Catalyzed and ZnI2-Promoted Preparation of Oxazolidines and Propargylamines Using Chiral Amines, 1-Alkynes, and Propiolates

Diphenylphosphinoethane (DPPE)-catalyzed and ZnI2-promoted in situ formation of oxazolidine, alkynyl zinc, and propargylamine intermediates from 1-alkynes, chiral (S)-diphenyl(pyrrolidin-2-yOmethanol, and propiolates gave the corresponding chiral (R)-beta-allenoates in 40-72% yield with up to >99% ee. The intermediate propargylamine was isolated in 50% yield and converted to give the beta-allenoate 10aa in 68% yield and 96% ee upon reaction with ZnI2. The results are discussed considering a mechanism involving oxazolidine and iminium ions formed in situ followed by addition of alkynyl zinc complex to produce the propargylamine that gives the corresponding allenoate via a 1,5 hydrogen shift in the presence of ZnI2.

Stereoselective synthesis of pinane-type tridentate aminodiols and their application in the enantioselective addition of diethylzinc to benzaldehyde

A library of pinane-based aminodiols were prepared from commercially available (1R)-(-)-myrtenol (-)-1. Compound (-)-1 was transformed into ally! trichloroacetamide (+)-2 via the acetimidate, followed by the Overman rearrangement. In order obtain the aminodiol structure, (+)-2 was subjected to stereoselective dihydroxylation with OsO4, resulting in dihydroxy trichloroacetamide (+)-3. The trichloroacetyl group was removed from (+)-3 with aqueous HCl and the (1R,2R,3S,5R)-3-amino-2-hydroxymethyl-6,6-dimethylbicyclo[3.1.1]heptan-2-ol hydrochloride (-)-4 obtained was transformed to primary, secondary and tertiary aminodiols by reductive amination, N-alkylation of aminodiol (+)-9 and debenzylation of N-benzyl aminodiol (+)-10, respectively. In the reactions of (+)-9 and (+)-14 with formaldehyde, highly regioselective ring closure was observed. In contrast with earlier results, the aminodiols gave pinane-fused oxazolidines (+)-11 and (-)-15. The aminodiols and their oxazolidine derivatives 5-15 were applied as chiral catalysts in the enantioselective addition of diethylzinc to benzaldehyde. The best enantioselectivity was observed in the case of the N-benzyl-substituted derivative (+)-9. (C) 2012 Elsevier Ltd. All rights reserved.
